I was wandering around Ebay and found these cheap, $47 delivered. I was wondering how difficult it would be to repair something like this or how much it would cost to have one repaired. I'm starting to get this need to "collect the rainbow" that I see others have and this would be a cheap way to get a 473 if they wouldn't be to great of a challenge or expense. I willing to try just about anything when it comes to disassembling and trying for a fix. Link below.

Ah, I didn't bother to look at his other items. Guess he goes on my watch list for now, too much spent on other laser related stuff for the moment. Thanks for pointing out the working version, although at some point I may try one of the nonfunctioning ones just for the experience of working on a DPSS.
